Investigating the spatial and temporal changes of travel pattern between 2005 and 2010 in Beijing
MetadataShow full item record
Since the economic reform of the 1980s, Beijing has been experiencing a tremendous increase in population and motorized vehicles, which brings an explosive rise in daily travel demand. Based on the road datasets with classification in 2005 and 2010 and travel flow data aggregated by traffic analysis zones of 2005 and 2010, this study aims to analyze the spatial and temporal pattern of traveling in 2005 and 2010 in Beijing as well as the changes over the 5 years. A spatial interpolation tool in ArcGIS was developed to interpolate travel flows to a common spatial zoning scheme, and the User Equilibrium Traffic Assignment was applied. The findings from this study will be particularly useful for transportation planners seeking information to understand the urban spatial structure, predict travel demand and improve the transportation service and management.
